AI Drawing Prompt Reference

Draw a pyramid shape. Start with a polygon of four points for the base, then construct the pyramid. Connect the base vertices with the pyramid apex and find intersections with the base. Connect these intersection points to form a new polygon. Then combine this polygon with the pyramid apex and the original base center to form a triangle. Finally, present this shape to describe the volume calculation of the pyramid.
